' In Sweden October 15, 1941 v y 6 claims.

The present invention relates to signaling devices for cycles by means ofwhich the driver gives notice of his intention to turn his vehicle to the right o-r to the left by means of electric lamps provided at the ends of the handle bar.

The main object of the invention is the provision of a signaling device o'f the kind referred to which is simple in construction and well protected against damage.

Some embodiments of the invention are shown by Way of example in the accompanying drawing, in which Figure l is a perspective view of a handle bar provided with a signaling device according to the invention; Figure 2 is a diagram of connection; Figure 3 is a longitudinal section through the one end portion of the handle bar with grip, lampv and switch; Figure 4 is a cross section through the handle bar and the grip along the line IV-IV in Figure 3, and Figures 5 and 6 longitudinal sections through modied embodiments of the invention.

Referring to Figures 1-4 I denotes the tubeshaped handle bar to each end portion of which a socket-shaped grip 2 is secured in a suitable manner. Each grip is provided with side openings 3 situated in front of side openings 4 in the handle bar I. In each end portion of the handle bar there is inserted and in a suitable manner fastened a cylindrical holder 5 for an electric lamp 6 situated in front of the side openings 4. The lamp holder 5 is also provided with a switch the xed contact member of which is indicatedv by 'I and the movable contact member of which comprises a metal spring 'la which contacts the inside of the handle bar and which is actuated by a push button 8 projecting through a side opening in the handle bar near the grip. The source of current for the lamps can be a dynamo 9 which is driven by the cycle and the one terminal of which is electrically connected to the front fork of the cycle. As clearly appears from Figure 2 the switches are so coupled in the connections I0 from the dynamo to the lamps that when the push button 8 at the left grip 2 is actuated the lamp 6 in the right end portion of the handle bar is lighted, and vice versa. Thus, the driver can make double signals when he intends to change the direction of movement of the vehicle, on the one hand by stretching out the one arm and on the other hand by lighting the corresponding lamp 6 by means of the hand still holding the handle bar. It may be suitable to cover the openings 3 in the grips 2 with prisms or lenses Il of a translucent and preferably coloured, f. i., red material.

(Cl. ITI-329) The embodiment shown in Figure 5 differs from Hthat shown in Figures 3 and 4 only in that respect that the grip 2 in its entirety is made of a translucent and strong material, f. i., red coloured Celluloid.

Also in the embodiment shown in Figure 6 the grip 2 in its entirety is made of a suitable, translucent, f. i., red coloured material. Thesocketshaped grip 2 is provided with aA bottom portion 2a exposed to the light from the lampY 6. The switch comprises a bow-shaped metal'springlll, which is connected lto one of the connectionsl. The'free branch I2 of the spring I4 is situated outside the 'handle bar I in a longitudinal groove I3 at the inside of the grip 2 and is actuated by a push button 8a projecting through a side opening I5 in the grip 2. vBy means of this push button 8a the branch l2 can be brought to contact the handle bar I thus closing the circuit to the lamp 5 provided in the other grip 2 of the handle bar. The device shown in Figure 6 requires evidently no openings in the handle bar.

The invention is not limited to the embodiments described above and shown in the annexed drawing but may be varied in details without departing from the spirit of it.

I claim: Y

1. An electrical directional signaling device for cycles having a tubular handle bar, a socket permanently secured within said bar, a lamp mounted within said socket having a supply of electric energy, a switch for controlling the supply of electric energy to said lamp, a hand grip permanently secured to said bar for completely housing the lamp arranged therein and at least a portion of said hand grip being translucent whereby the light rays from said llamp may pass therethrough and emit therefrom.

2. An electrical Isignaling device for cycles having a tubular handle bar and the outer end of said bar being open, a socket permanentll7 secured within the outer opened end of said bar, a lamp mounted within said socket, lead wires extending throughsaid tubular handle bar for supplying electrical energy to said lamp, a switch for controlling the supply of electrical energy arranged Within said bar and connected to said lead Wires, a hand grip permanently secured to and extending over the outer opened end of said bar and a portion of said hand grip being translucent,

whereby the rays of light from said lamp may pass therethrough and be emitted therefrom.

3. An electrical signaling device of the character described comprising a tubular bar having its outer end open, a socket secured within vsaid 3 bar, a lamp mounted within said socket, lead wires extending through said bar for supplying electrical energy to said lamp, a translucent hand grip secured to and extending over the open end of said bar, a spring actuated switch arranged its outer end open, a socket permanently secured within said bar, a lamp mountedwithin said socket, lead wires extendingv through said tubular bar for connection with said lamp insupplying electrical energy thereto, a translucenthand gripv permanently secured to and extending over the open end of said bar for completely housing the lamp Varranged therein, av switch comprising a Ybow-shaped'metal spring having one end connected rto one ofsaid lead wires, said tubular bar being made of metal and grounded and a push button extending through said hand gripand connected to the opposite or free end of the metal spring of said switch whereby the latter may be attimes brought into electrical contact Withsaid 'bar for causing said lamp to glow andthe light rays thereof to emit therefrom and pass through said translucent hand grip.

5. An electrical signaling'device for cycles having a tubular Yhandle bar, said tubular handle bar having an arrow shaped'light emitting opening therein, a socket arranged within said loana lamp mounted within said socket having a supply of electric energy, a hand grip permanently secured to said bar, a lense arranged Within 'said hand grip and extending over the arrow shaped opening within said bar, and a control switch mounted y said hand grip fol' controlling the supply ofelectrical energy to said lamp.

6. An electrical signalling device for cycles'having a tubular handle bar, said bar having light emitting openings inthe sidewalls thereof, a 'socket permanently mounted within said bar, a lamp mounted within said socket having a, supply of electricalenergy, a hand grip secured to and encasing said bar and said hand grip'havng arrow shaped light emitting openings therein registering with the openings inthe side Vwalls of said bar whereby the rays of light from said lamp may pass therethroughk and emit therefrom.Y
